This review aimed to explore the current literature on effect of diaphragm release, vagal stimulation and Cervical SNAGs on B.P, Heart Rate and skin hydration in prehypertensive individuals. The studies published in the English language between 2000 and 2023 were included based on a search of the databases PEDro, PubMed, and Google Scholar. Studies that examined the effect of diaphragm release, vagal stimulation and Cervical SNAGs on B.P, Heart Rate in prehypertensive individuals were included in this literature review. We found a total of 44 studies describing the effect of these three intervention included in this literature review. Vagal stimulation was found to have positive outcomes in 33 studies, while 11 studies had contradictory conclusions. Based on our findings, vagal stimulation is widely used for the rehabilitation of prehypertensive individuals. The parameters used to assess the improvement mostly included Heart Rate, B.P and skin hydration. The outcome measures used in studies are usually linked to body’s sympathetic control system. However, there is a scarcity of studies on the effect of vagal stimulation which should be the outcome of any Prehypertension rehabilitation program. There is scope for future research to demonstrate the effect of vagal stimulation and its comparasion with diaphragm release and Cervical SNAGs in prehypertensive individuals.
